New Lens?

[JA_Photography]

Hey everyone,
I am in the market for a new lens. Looking for a wide angle low aperture lens. I already have the 50mm f/1.8 and I love it. But am looking for a little bit wider. I was wondering if anyone has had any experience with any of these types of lenses. Any insight would be much appreciated.

Here was one lens that I am considering.

look into the tokina 12-24mm f4. It's amazing for car photography..

I heard good things about the 30mm Sigma. However, my next purchase will be the 14mm Rokinon. MF lens, but amazing sharpness and bokeh. Also, the 35mm Rokinon. :)

If you're looking for a fisheye, the Rokinon 8mm is awesome and it's only 300 bucks. Here are some shots I've taken with it.
